EDWARD EVEREATT GAGE, (3F NEW YORK, N. Y.

aEMtEI-GLGCK.

To all -u m ti concern:

Be it l. own that I, EDWARD Evnans'rr GAGE, a citizen or" the United States, and re siding at New Yorir, in the county of New York and State or" New York, have invented cs min new useful Improvements in Alarn1-Cloclrs, of which the following is a specification, such as wld enable those skilled in the art to which it appertains to make and use the same.

Tins invention relates to alarm clocks, and

the object thereof is to provide an ordinary alarm clock having an'ialarm dial, and a hand movable over said dial and adapted to be set so that the alarm will be sounded at any hour, or certain fractional parts of an hour, with supplemental alarm setting devices whereby the alarm may be set to go oil at any minute during the day or night,

and means whereby the alarm maybe thrown out of operation whenever desired.

The invention is fully disclosed in the fol lowing specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are desig-.

nated by suitable reference characters in each of the views, and in which Figure 1 is a face view of an ordinary alarm clock provided with my improvement; Fig. 2 a similar view with the front glass and dials removed and the case shown in section Fig. 3 a sectional side view of the clock as shown in Fig. 1; Fig. 4 a side view ofa spring lever which I employ; Fig. 5 an edge view thereof; Fig. 6 iace View of another s rin lever which I emnlo l i 7 an ed e View thereof; ljr ig. 8 a sectional side view of the minute hand sh at t or arbor and the parts mounted thereon in operative connect-ion therewith; Fig. 9 a section on the line 9. 9 of Fig. 8; Fig. 10 a perspective detail view f the esoapement shaft, a trigger connected therewith and operating spring levers which I employ and, Fig. 11 a section of a rotatable annular dial which I employ, said section being on the line 11-1 1 of Fig. 1.

In the drawing forming part of this specification, reference being made to Figs. 1 to 3 inclusive, 1 have shown an alarm clock of the usual form and v hich comprises a case a in which the usual chock mechanism or time mechanism is placed, the latter being mounted in a frame I) secured in the case, and the time mechanism is in all respects similar to of other clocks of this class, and the said clock is provided on the ma n dial a thereof 4 ossification of Letters Eatent.

with a sup lemental alarm dial a having an alarm set and o which is connected with the shaft a in the usual manner. The clock mechanism is provided with the usual minute shaft or arbor (Z with which the minute hand d is connected and with the hour sleeve or arbor e with which the hour hand e is connested, and in the practice of my invention, I provide an intermediate or third arbor 0 through which the *shaft or arbor d passes and on which the sleeve or arbor e is mounted, as clearly shown in Figs; 8 and 9. The

sleeve or arbor c is provided with an alarm Mounted on and rotatable on the outer portion or" the main dial a is a rotatable. minute dial f having an outwardly directed annular flange f on which the glass g is placed, and said glass is held in place by a flange or rim a on the clock case, and said glass also rotatable'with the dial f. dial f is divided into twelve equal parts, each of which is provided with five subdivisions representing minutes, said parts being numbered from one to sixty from left to right, and the dial f is also provided with an inwardly directed lug or projectionf in connection with which the operating hand 0 operates as hereinafter described. The front glass 9 of the clock is provided near its outer edge with a peg which passes through a suitable aperture formed therein, and by means of which the hand 0 and the rotatable dial f are operated, and the case of the clock is provided at a? with a door or opening'for the purpose of determining when the alarm spring is run down, notice of which is given by the said door being raised by said spring as it unwinds, this position of the door indicating that the alarm spring should be wound up. 71. pivoted to the lower right hand corner of the-frame b at h and extending u iwardly and diagonally across the front of t e clock mechanism and rejecting through a slot in the case a, and the upper endportion k The I I also provide a spring levcr of which forms a handle by means of which I Q m n 7 the said s ring lever is also provided with an aperture 7 through which rbors c and a pass, and said aperture is en arged to permit of the movement of the spring lever oirsaid arbors so that the operator may throw the alarm mechanism into or out of operation at any time by simply moving the handle portion k of said lever up or down as may v be required.

The spring i which in a clock of this class is secured to the upper right hand corner of the frame 7) shown at if, and which is provided with a lug i which also operates in connection'with'the trigger Ii" is also employed, and said spring i is also provided with an enlarged aperture '1'. through which the alarm shaft o and sleeve mounted thereon pass, the aperture i being enlarged so as to permit of a slight movement of the spring I end of the arbor c with which the operating or supplemental alarn'i setting hand c is connected is provided with a llai'igeg' having a tooth 0 adapted to operate in the cam recess in said gear and the spring lever h presses on the flange 0 and tends to hold said flange and the minute gear in connection, and the arbor c is movable longitudinally on the arbor cl. V

- The glass 9 and the annular rotatable dial f are normally held stationary by friction,

but when an operator desires to set the suplemcntary alarm mechanism the 0 oration is as follows. Suppose .it is desire to set the alarm mechanism so that said alarm will go off at twenty and a half minutes past nine as shown in Fig. 1. The regular alarm device is set for nine oclock as shown in Fig. 1, and the operator takes-hold of the peg g and turns the glass 9 tov the left, in which 0 oration the operating hand a is picked up,

a ter which the end of the hand 0 engages the lug ,or projection f 3 on the dial f, after which the said hand c and dial f are turned until the minute hand (1 and operating hand 0 are both in the same line at which time the hand a is automatically released from the dial f by the action of the spring lever it upon the flange c of the arbor c and the tooth c dropping into the recess 7' The indicator hand 0 is then turned until it reaches the line of mark representing twenty-one minutes, or the twenty-first line or mark to the right of the sixty minute mark on dial and said hand is left in that position.

The escapement shaft h is provided with the usual escapcment h and with the hammer 71, of the alarm device which operates in connection with the hell or gong I: in the usual manner, and it will be understood that the construction and operation of the clock mechanism other than as herein modified and described is the same as that of other clocks of this class. The projecting portion in" of the spring t which passes through the casing c of the clock converts said spring into a lever and forms a handle by whichit may be operated to throw the alarm. device into or out of operation, and it will also be under stood that as long as either the spring lever i or the spring lever 11" is in engagement with the trigger h which is secured to the escapeg0 mcnt shaft It, the alarm device cannot operate. lt will also be observed that the indicator or operating hand c is located between the hour and minute hands and is adapted I to move freely and independently of said 55 hands.

By extending the end of the s ring i through the casing of the clock and 'orming the same into a lever the main alarm mechanism maybe thrown into or out of ope ation, whenever desired, thereby allowing tlw hour/ or minute alarm setting mcchanism to be used separately or conjunetively.

My improved setting mechanism for alarm clocks is simple in construction and opera- 5 tion and may be applied to any clock of the class described, and changes therein and modifications thereof without sacrificing the advantages of my invention or departing from the spirit thereof set out in the ap 0o pended claims.

Having fully described my invention, what I claim as new and desire to secure by Let.- ters Patent, is

1. An alarm clock provided with a sup-' 0:, plemental alarm set dial, and means whereby the alarm may be set to operateat any hour or fractional parts thereof, and supplemental alarm set devices whereby the alarm may be set to operate at any minute of the day or 10 night, comprising an annular rotary minute dial mounted on and inclosing the hr dial of the clock, a supplemental arbor i mounted on and rotatable on the arbor and on which the hour arbor is mount- 11 5- ed, said supplemental arbor being provided on its inner side with a tooth adapted to enter a recess in the minute gear, a spring lever pivoted to the frame of the clock mech anism and provided with an aperture through 12o which the supplemental arbor passes, said spring lever being, passedout through the casing of the'clock and adapted to be operated by hand, and an operating hand connected with the supplemental arbor and adapted during its rotation to engage and carry with it the annular minute dial and to be automaticall released therefrom at a predetermined time, said spring lever being also adapted to engage a trigger connected bination with a spring lever mounted on the with the escapement shaft with which the hammer of the alarm device is also connected. 2. In a clock alarm setting mechanism a supplemental tubular arbor mounted between the hour and minute arbors and provided at its inner end with a tooth adapted to engage a cam recess in the minute gear, and an indicator operating hand connected with the supplemental arbor and movable between the hour. and minute hands, in combination with a spring lever mounted on the inner end of the supplementalarbor and one end of which is secured to the framework of the clock mechanism, said spring lever being adapted to engage a trigger secured to the escapement shaft.

In a clock'alarm setting mechanism, a supplemental tubular arbor mounted. between the hour and minute arbors and provided at its inner end with a tooth. adapted to engage a cam recess in the minute gear, and an indicator operatinghand connected with the supplemental arbor and movable between the hour and minute hands, in cominner end of the supplemental arbor and 'one end of wh ch is secured to the framework of the clock mechanism, said spring lever being adapted to engage a trigger secured to the escapement shaft, and the free end 01,

said lever being projected through the casing of the clock.

4. A sup lemental alarm setting mechanism for c ocks, comprising a supplemental arbor mounted between the hour and minute arbors and provided with an operating hand movable between the hour and minute hands the supplemental arbor being provided at its inner end with a tooth adapted to engage a cam recess in the minute gear, a spring lever pivoted to the framework of the clock mechanism and adapted to move the supplemental arbor longitudinally and to engage a trigger secured to the escapement shaft, an annular rotary minute dial inclo'sing the hour dial of the clock, a rotary glass inclosing the dials of the clock, and a pin operating in connection with the operating hand and passing through said glass, said operating hand'being adapted in its rotation to engage. the annular minute dial and to release the same at a predetermined time.
